. Referring to Figs. 1 and 2 of the drawings, 1 indicates the hub and 2 the periphery of a wheel, which, when equipped with my novel detachable, sectional rim, is. particularly adapted for use as the body of a transmission or differential gear of a motor vehicle. The periphery, 2 has a substantially flat face 2 and is provided with an annular rim or flange, 3 to which the rim islsecured. Although, when using the gear for thepurpose mentioned, I prefer the construction of .7? all aw/mm. it may concern:

Bi.- it known that I, SIMON STDFFEL, a citim-n ol' the United States, residing at West .d -lh-my. in thecounty of McHenry.and i'ilill ol' lllinois, have invented certain new and useful improvements in Sectional Wheels for Power Transn'iission, of WlliOlt'thG following is a specification.

My invention relates to power transmisslim \\'ll('(l and. has particular reference to din rims nl' sectional power transmission or you! \.'lil' 'lr-.

the wheel body as shown and described, the body may be formed in any preferred manner.

The rim c'omprisesa plurality of similar segmental sections, 4 having a gear surface formed on the outcrface. This may take the form of the spur gear teeth, 5 shown in Figs. 1, i2, 3, 5 and 6; the bevel ear teeth shown in Fig. 4; or the groove; illustrated in. Fi s. 7 and 8. The sections are provided wit 1 a longitudinal groove, 8, )rovido a i when a. wheel body' having the annular huhly se- I flange, 3 is used, ,Iiowcvcr, when the rim is wilh lhn transmission and differential gears rm motor vehicles and occasions considerable u1i!|o \um' c inasmuch as when such an acci- I dinl ur'l'lll'h', the gearing has to be taken (0111- ph-tr-ly apart. and the broken gear replaced I with a pui'iect one.

'lluobject of my invention is to goal wheel rim which may be dot-ac f, cured in any suitable wheel. or pulley to transform the same into a gear wheel oi the rhnrnl-tcr desired. 4 i A further object is to provide a sectional rim adapted to be detachably secured to the periphery oi a wheel to the end that the rim or any portion thereoi'may be replaced, when mutilated. without removing or disturbing the alincnwnt oi the wheel-or its shaft.

Further objects will appear hereinafter. will be more readily undnrreference to the accompanying partoi' this spnciiicm ion to be used upon a wheel having a -flat pe. riphcry, the rim may or may not he formed groove, 8, as desired. When such a provided the sections of the rim are Iplurality of bolts, 9 t holcs Q in the rim with the flange is secured thereto byj'a which JttSS through b0 and holes 3 in the flange, 3. To secure the abutting ends of the sections to e'tl'icr, I proride a bolt, 10 assing througi diagonally arranged bolt ho cs, 10 in the adjacent ends as shown in Fig. 3.

The base of the rim sections, 4, are providnd with flanges, 11 extending laterally therefrom.

To this, end the flanges, 11 are provided with bolt holes, 12, to receive the bolts, 13 where stood by tll'it\\lll; f:- forming a. and in which,
